TDI/TRIMELLITIC ANHYDRIDE COPOLYMER

Description

TDI/Trimellitic Anhydride Copolymer is a synthetic polymer used in various skincare and cosmetic formulations. This copolymer is created through the reaction of toluene diisocyanate (TDI) and trimellitic anhydride, resulting in a substance with unique film-forming and adhesive properties.

In skincare products, TDI/Trimellitic Anhydride Copolymer functions primarily as a film former and viscosity control agent. It creates a thin, flexible film on the skin's surface, which can help improve the longevity of other active ingredients and provide a smooth, even application. This copolymer is particularly useful in long-wearing makeup formulations, such as foundations and mascaras, where it enhances product adherence and resistance to smudging or transfer.

The ingredient also contributes to the stability and texture of formulations, helping to maintain consistent viscosity and prevent separation of components. Its water-resistant properties make it valuable in products designed to withstand perspiration or humidity. While generally considered safe for cosmetic use, individuals with sensitive skin or a history of allergic reactions should perform patch tests before widespread application of products containing this copolymer.
